Orlando recently wrapped up its annual weeklong Gay Days festival on June 6 in which up to 150,000 in the LGBT community attend area theme parks, gay nightclubs and special events. It was the 25th anniversary of Gay Days. It is one of the largest gay pride events in the world.

And it’s not stopping as we see apparently today. More of these attacks are coming. It’s a real part of the threat that we face and if we can’t address it openly and directly, and say directly that there is an extremist element within Islam, that’s dangerous to the world and has to be confronted.

Update 8:22 am ET: The FBI believes the massacre may have perpetrated by someone “leanings to radical Islamic terrorism.”

ORLANDO, Fla. (AP) — A gunman wielding an assault-type rifle and a handgun opened fire inside a crowded Florida nightclub early Sunday before dying in a gunfight with SWAT officers, police said. The attack left at least 20 people dead and 42 others wounded.

Authorities were investigating it as an act of terrorism.

The suspect exchanged gunfire with an officer working at the gay club known as Pulse Orlando around 2 a.m., when more than 300 people were inside. The gunman then went back inside and took hostages, Police Chief John Mina said.

Around 5 a.m., authorities sent in a SWAT team to rescue the hostages. Police have not determined an exact number of casualties, but Mina said “approximately 20” bodies were inside the club.

In addition to the guns, the shooter also had some sort of “suspicious device,” Mina said.

Authorities were looking into whether the attack was an act of domestic or international terror, and if the shooter acted alone, according to Danny Banks, an agent with the Florida Department of Law Enforcement.

“This is an incident, as I see it, that we certainly classify as domestic terror incident,” Orange County Sheriff Jerry Demings said.
